The circulation of the dengue virus continues to spread in our territory. Public Health France confirms a 28% increase in the number of patients seen in city medicine for dengue syndrome. The number of outbreaks is also increasing.

The dengue epidemic is gaining ground.
In the past 2 weeks, from June 26 to July 9, 160 patients seen in city medicine were carriers of the dengue virus, compared to 125 in the previous weeks. The increase is similar for home visits made by SOS Medecin with around twenty visits over the past two weeks compared to a dozen visits over the previous weeks (June 12 to 25).
A few dozen dengue cases have been exported to France since the start of the upsurge in cases. The dengue virus strain, the DENV-2 serotype, was identified in a majority of the cases investigated.

Since the beginning of 2023, 200 confirmed cases of dengue fever have been detected, 24% of them in the last four weeks. The municipalities with the highest number of cases are Sainte-Anne (59 cases) Trois-Ilets (48 cases). During the last two weeks (between June 26 and July 9), confirmed cases of dengue were recorded in 9 municipalities: Trois Ilets, Le Diamant, Schoelcher, Rivière-Pilote, Saint-Joseph, Sainte-Anne, Trinité, Marin, Ducos and two cases with an unknown address.
Viral circulation remains active in Trois-Ilets with an active epidemic focus in Anse à l’âne.
Over the past month, twelve municipalities have reported confirmed cases of dengue fever:
6 towns to the south (le Diamant, le Marin, Rivière-Pilote, Sainte-Anne, Ducos and Trois-Ilets) 3 towns to the north (Saint-Joseph, Saint-Pierre and La Trinité), 3 towns in the center (Fort -de-France, Schoelcher and Lamentin)
This geographic surveillance of confirmed cases demonstrates, according to SPF (Public Health France), the slow expansion of the virus.
In view of the continued resurgence of dengue fever cases and the active circulation of the virus, theARS has raised the level of surveillance to phase 2- level 2 of the PSAGE, namely, “focus with evolutionary potential or multiple outbreaks with epidemiological links between them”. This phase change calls for increased vigilance and control measures once morest the Aedes Aegypti mosquito, vector of dengue fever.
Epidemiological surveillance carried out in conjunction with private laboratories, the Martinique University Hospital and sentinel doctors has been reinforced.
Vector control interventions implemented around confirmed cases are continuing. Similarly, disinsect control operations in aircraft are carried out with ARS teams.
Health authorities recommend that you protect yourself and avoid encouraging the laying of mosquitoes by regularly emptying containers likely to retain fresh water.
